Choosing the right power regulator for Battery powered designs
I often do microcontroller projects and often want them to be powered by a 3.7V Lipo cell charged by a standard microusb cable. This means input voltage can range from 3.0V to 5.0V and I want an output voltage of 3.3V. The more power it uses, the less battery power is left for your device. LDO''s generally have much smaller quiescent current

Battery Selection for MSP430
To get the number of hours a battery will last I believe I would just take [rating in amp hours] / 220uA. If I were to have a battery rated to 220 mAH then this microcontroller would last ~ 1000 hours in active mode. Is "active" mode simply with the chip in active mode while it''s idle? 1k hours seems absurdly long for a small battery.
Switch between battery and USB power
When USB voltage is present Q1 is trurned on by R2/R3 and this turns on Q2 (usually held off by R1) which clamps Q3 gate high turning it off, thus disabling battery feed. USB power feeds via D1 either via Ja and LDo or Jb as above.

6 FAQs about [Battery to power the microcontroller]
Can a microcontroller be powered by a battery?
The goal is to have an energy source that outputs the microcontroller’s required current and voltage. While microcontrollers can often be powered by a direct or alternating current, for added security, many developers use external batteries to support necessary functions.
Why should you use a battery for a microcontroller?
Additionally, batteries enable devices to go cordless. A device that doesn’t need to be plugged into a wall can be more easily transported. When using current microcontroller battery technology, there are certain limitations because a battery can only provide so much power for so long.
How many volts a battery can a microcontroller handle?
But the issue with these batteries is that most of these batteries are rated for 3.7 volts and a maximum of 4.2v. Now for our application we generally need either 3.3v or 5v because typical microcontrollers and sensors work on these voltage levels. So in order to get the right voltage you either need a buck converter or a boost converter.
Can a microcontroller function without a power supply?
Microcontrollers cannot function without a power supply. They have no built-in battery, meaning they are powered with external sources. The goal is to have an energy source that outputs the microcontroller’s required current and voltage.
What is the most power-efficient microcontroller (MCU)?
Silicon Labs designed the EFM8 8-bit microcontroller (MCU) family from the ground up to be the most power-efficient MCUs in the industry. The combination of the low active mode current consumption when the application is running and the industry’s lowest current consumption in sleep modes saves power in real world embedded system.
How long do microcontroller batteries last?
Electrochemical microcontroller batteries only last a fraction of the time that newer betavoltaic power sources do—and they degrade from frequent usage. Our tritium battery products have been tested to last longer than two decades and perform without permanent degradation under extreme external conditions.
